Prostomium (sometimes also called acron) is the first body segment in annelids worms. It is in front of (but does not include) the mouth, being usually a small shelf- or lip-like extension over the dorsal side of the mouth. It sometimes bears antennae and eyes. By feeding, it often functions like a kind of overlip. The shape and composition of prostomium are important for annelid systematics.
